Chapter 2: Probing and Selecting the Sampling Mode
Choosing the Sampling Mode
configuration, the input reference clock edges can occur at rates up to 800
MHz.
You can choose from:
• 800 Mb/s / Eye Scan
In this configuration: Either rising, falling, or both edges of the input
reference clock can indicate valid data. All of the logic analyzer
channels are available. The maximum number of clocks that can be
processed at each scan point is 60,000,000.
• 1500 Mb/s / Eye Scan
In this configuration: Both edges of the input reference clock indicate
valid data. Only half of the logic analyzer channels are available. The
maximum number of clocks that can be processed at each scan point is
120,000,000.
To set up the eye scan mode reference clock
For the clock input signal that will be used:
1. Select the pod's Master button (under the activity indicator).
2. Select whether data is valid on the Rising Edge, Falling Edge, or Both
Edges.
In the 1500 Mb/s / Eye Scan speed configuration, data must be valid on
Both Edges.
